Definitions

  • the invention relates to a cylinder lock comprising an outer cylinder with two 180 0 offset longitudinal grooves, freely movable with a rotatably disposed in the outer cylinder the inner cylinder having at least two guide slots of the inner cylinder, springless plate-shaped tumblers, which engage in the locked state in one of the longitudinal recesses of the outer cylinder and the Block the inner cylinder against twisting, which are provided with windows for a key and which, when the corresponding key is inserted, are positively controlled by the key profile in both directions of movement, from the area of the longitudinal groove to the area of the inner cylinder, the open position, and thereby the inner cylinder becomes rotatable.
  • Such a cylinder lock can now be opened quite easily by an unauthorized person by inserting an object through the window into the plate-shaped tumblers which is jammed on the side surfaces of the window.
  • the tumblers lying in the same plane can all be lifted together out of the longitudinal groove until they come to lie within the dimensions of the rotatable inner cylinder and the inner cylinder can thereby be rotated.
  • Means for carrying out this method are known, so that these types of locks offer only limited security. In particular for locks in which the tumblers are not spring-loaded, this method can easily be used due to the free movement of the plates.
  • the inner cylinder When scanning the locking edges of the tumblers, the inner cylinder must be rotated so that the tumblers rub with their locking edges in the guide slots. The locking edges can then be felt when the tumblers are lifted. Locks are also known which make this scanning of the locking edges difficult.
  • the tumblers and correspondingly the longitudinal recess in the outer cylinder of the lock, in which the tumblers engage in the closed state are provided with profiles and hooks which are intended to prevent the tumblers from lifting after the inner cylinder has been slightly twisted. This measure makes unauthorized opening of the lock more difficult.
  • it is still possible to manipulate the tumblers directly through objects inserted into the key channel it is only a matter of time and skill to open such a lock.
  • the object of the invention is therefore to provide a cylinder lock with plate-shaped tumblers, which is safer against unauthorized opening without a key and at the same time simple in construction, inexpensive to manufacture and functionally reliable.
  • a preferred embodiment consists in attaching a guide profile in the rotatable inner cylinder, into which continuous protective strips are inserted after the insertion of the tumblers into the guide slots in order to cover all the side flanks of the tumblers present in the cylinder lock and located in the area of the key guide. Since the protective strips must lie on the one hand within the window cutouts of the tumblers and, on the other hand, must be firmly connected to the rotatable inner cylinder, a simple assembly and cost-effective embodiment is achieved by inserting protective strips into a guide profile of the inner cylinder after the tumblers are inserted.
  • the cylinder lock is constructed from individual sections, the separating surfaces of which lie in the region of the tumblers.
  • the protective strips in conjunction with an adapted window size serve as stops for the tumblers in the locked state.
  • the window cutouts With appropriate selection of the window cutouts, it can thereby be achieved that the individual tumblers are immersed in the longitudinal recess on the outer cylinder in the locked state at different depths.
  • Raising the tumblers together into the open position of the lock is hardly possible anymore due to the protective strips arranged on the side in the key channel, since the upper and The lower edges of the tumblers are already at different heights according to the key profile, but as additional security the different immersion depths proposed here can be included in the lock.
  • a lock housing 1 in which an outer cylinder 2 is arranged non-rotatably.
  • An inner cylinder 4 is rotatably mounted in the outer cylinder 2.
  • the outer cylinder 2 has longitudinal recesses 3 on the bottom and top.
  • Plate-shaped tumblers 5, 6- are arranged in guide slots 8 of the inner cylinder 4. (For a better overview, the tumbler plate 6 is not shown in FIG. 1, but rather only its place in the guide slot 8 is designated.)
  • a key 7 is inserted into the cylinder lock in FIG. 1 and thus the tumbler plates 5, 6 are out of the lower longitudinal recess 3 raised to the open position and close on their outer sides with the outer surface of the rotatable inner cylinder 4.
  • the key 7 has the same profile width 15.
  • the inner cylinder 4 is removed from the lock and cut at the location of a guide slot 8 with the protective strips 10, 10a inserted.
  • the protective strips 10 and 10a extend over the entire length of the cylinder lock. 2 also shows an appropriate profile design of the protective strips 10, 10a and a corresponding profile design of the rotatable inner cylinder. To connect to the rotatable inner cylinder 4, the protective strips 10, 10a are simply pushed into the profile recess.
  • Fig. 3 is a section transverse to the cylinder lock at the location of a tumbler with an inserted key corresponding to FIG. 1 is shown.
  • the key 7 is designed here as a double key with the profiles 7a and 7b.
  • the tumbler plate 5 has on its lower side surface a notch 13 which, in the locked state (FIG. 4), lies against an edge 11 of the outer cylinder.
  • Fig. 4 it can also be seen that the protective strips 10, 10a can be used as stops for the tumblers sliding downwards.
  • the individual tumbler plates can thus be brought to different heights in the locked state by appropriately designing the windows of the tumblers.
  • the tumbler plate shown in FIG. 4 has, for example, a small immersion depth in the longitudinal recess 3 when it is rotated through 180 ° when it is used for the second profile of the double key.
  • the notches 13 on the outer edge of the tumblers 5 serve as a further protective measure against unauthorized opening by scanning the tumbler plates.
  • the notch 13 would get caught on the edge 11 if the inner cylinder 4 were turned slightly.
  • this notch in particular would allow the inner cylinder to rotate slightly and thus possibly to scan the locking edges of the tumbler plates.
  • the notches are only attached to one end of the tumbler plates 5, so that when this tumbler plate rotated 180 0 used as the tumbler plate 6 for the opposite key profile of the double key 7, no rotation of the inner cylinder 4 is possible.
